While driving in heavy traffic on april 25, 2009, my 2004 volvo xc90 began jerking and then there was a sudden loss of power, the instrument panel swooped to the far right and then back to left with no other movement, the radio shut off, the windshield wipers began wiping, and the door locks and windows would not work. shortly thereafter, the message box displayed "brake failure-stop safely", and then changed to "srs airbag _service urgent". once we stopped, the vehicle would not start again. i disconnected the battery in hopes of resetting the computer. once this was done the car started again. messages are still displayed. we contacted volvo corporate and have an appointment with a local dealership tomorrow. this is a serious safety issue and it is not the first time i have submitted a complaint for this same type problem. i have been a faithful, repeat volvo customer, and would like to continue to support volvo. my loyalty is slowly fading, especially after reading several complaints of the same nature. volvo please don't let a death occur before you take action. *tr
